Abstract
The invention discloses a water treatment method for circulating water land-based aquaculture. The method is realized in a circulating water land-based aquaculture device. The water treatment method comprises the following steps of: (1) purifying aquaculture water in a water biological purifying device, then, introducing the aquaculture water into a culture pond body in a tangential direction by virtue of an oxygen-enrichment water elevating device, gathering aquaculture dirt in a drain outlet, and introducing the aquaculture dirt into the water biological purifying device through a water outlet; and (2) gathering the aquaculture dirt in the culture pond body to the center of the pond bottom, draining the aquaculture dirt through the drain outlet, introducing the aquaculture dirt into an aquaculture dirt separating device, discharging solid dirt, and introducing the separated clear water into the water biological purifying device for being recycled. According to the water treatment method, a tangential water-inlet circulating mode is adopted, so that the capacity and the effect of gathering the aquaculture dirt are remarkably strengthened; and meanwhile, water elevating, oxygen-enriching and water circulating are combined together, so that self-purifying internal cycle of aquaculture water body is realized and the integral energy consumption is only about 20% of that in the prior art, and therefore, the water treatment method has relatively great economical and social benefits.
Description
Technical field
The present invention relates to a kind of method for treating water of continental rise aquaculture.
Background technology
Aquaculture is an important component part of agricultural production, wherein: continental rise aquaculture mode has become an advanced technology in aquaculture and the part becoming heavy gradually.Adopt the aquaculture of cycle water continental rise, reliably producing the aquatic products of green safety, being of great significance realizing low-carbon (LC) fishery, recycling economy and structure China Modern Fishery tool.
But the development of current continental rise aquaculture, receives the restriction of factors, water source that is sufficient, that meet the requirements is that continental rise aquaculture institute is requisite, and insufficient water sources, water pollution problems, annoying the development of continental rise aquaculture always.Therefore, promote cycle water continental rise aquaculture technology level and more seem urgent and necessary.
In order to can water resource be made full use of, the water in culturing pool is recycled, manyly patent discloses respective technology, as Chinese patent, application number: 2004100536481 disclose a kind of industrialized aquiculture comprehensive treatment method for wastewater and treatment system.For the wastewater treatment of industrialized aquiculture.The waste water being rich in the metabolite such as ight soil and ammonia and residual feed bottom industrial aquaculture pond is transported to tilted plate separator, the ight soil that particle diameter is larger and residual feed are deposited in settling zone, then by mechanical filter, ight soil less for particle diameter and residual feed are tackled district before filtration, it is the biofilter of medium that waste water enters with nitrifying bacteria again, utilize nitrifying bacteria that ammonia is converted into nitrate, waste water is back to culturing pool again and recycles, tilted plate separator settling zone and mechanical filter filter the flocculate that accumulates bottom the ight soil of proparea accumulation and residual feed and biofilter and the sediment plant filter that to be regularly transported to water planting straw or like vegetable be medium, cyclic irrigation water planting straw or like vegetable is to complete interception and the nitrate of solids, the absorption even depth process of microcosmic salt etc., and regularly backflow carries out backwash to mechanical filter.
Norway A Kewa (AKVA) company also provides the aquaculture of a kind of industrial circulating water continental rise and comprehensive treatment method for wastewater and treatment system.
Culturing pool and quality purifying device for water are the critical components in continental rise aquaculture installation equipment, but in above-mentioned disclosed technology, the structure of its culturing pool is reasonable all not, the process of culturing pool, need the water lift through at least 2 ~ 4 times, the processing requirements of expection can be reached, cause cycle water continental rise aquaculture energy consumption large, operating cost is high, is difficult to apply.
Summary of the invention
The object of this invention is to provide a kind of cycle water continental rise aquaculture method for treating water, to overcome the above-mentioned defect that prior art exists.
Cycle water continental rise aquaculture method for treating water of the present invention, is characterized in that, realizes, comprise the steps: in a kind of cycle water continental rise aquaculture device
(1) aquaculture water in breeding production process, in quality biological purification device, by quality biological purification component purified treatment, water after process is by oxygenation picotan, wrapped up in by air and take lifting, by water inlet, cylindrical culturing pool body is entered with tangential direction, the water body of taking advantage of a situation in promotion culturing pool body, formed and continuously rotate fluidised form, cultivation dirt is made to focus on sewage draining exit, and form the effect of the height of water after oxygenation picotan water lift under, quality biological purification device is again entered by delivery port, form the circular flow back and forth used, for breeding production,
(2) the cultivation dirt in culturing pool body, then under the effect of rotary water current centrifugal force, assemble to the center at the bottom of pond, discharged by sewage draining exit, enter cultivation separation device of sewage discharge, the solid dirt discharge be separated first, the clear water after being separately then separated sends into quality biological purification device by circulating pump, again recycles;
The present invention is suitable for any kind cultivation of sea water and fresh water.
The invention has the beneficial effects as follows:
The present invention, on the basis of circular culturing pool, adopts the endless form of tangent line water inlet, and ability and the effect of assembling cultivation dirt been significantly enhanced; The circulation of water lift, oxygenation and water is combined simultaneously, more energy-conservation, achieve the low energy consumption self-cleaning Inner eycle of breeding water body, structure is simple, floor space is little, water in culturing pool is only through a water pump lifting, and overall energy consumption is only about 20% of prior art, has larger economic and social benefit.
